Sugar derivatives of 3-hydrazino-1,2,4-triazino [5,6-b] -indole and their periodate oxidation products

The reaction of 3-hydrazino-1,2,4-triazino[5,6-b]indole [1] with a number of sugar including an aldose, ketoses and a deoxysugar as well as a disaccharide has been investigated. Reaction of dehydro-L-ascorbic acid with 1 gave the bishydrazone 12. Reaction of 14 with 1 gave the mixed bishydrazone 15
